In the form as shown in Figures 1 to 6 in clusivethe blade holder comprises a body of stamped or pressed sheet metal arranged as an elongated body portion comprising stri a bottom section 16 shaped as a shallow V to provide oppositely inclined side facesl? and 18 having fiat edge flanges 19 and 20 respectively. Substantially one-half of the holder comprises a handle portion formedby overlapping on the base portion 16 a complemental handle portion 21 having a flat'edge flange 22 which is adapted to be welded or otherwise suitably secured to the edge flange 20 of the bottom section, cooperating therewith to provide the handle for the holder. This upper portion 21 of the handle is intebottom section being folded over from one side edge as shown in Figures 3 and 7. i

At its outer extremity the other half of the bottom portion 16 terminates in an upstanding perpendicular lip 23 which 'is centrally slotted as at2 to receive therethrough the tongue 25 of a top or upper clamping section 26 which is of a length sufficient to overlie thatportion of the base 16 which is not taken up by the handle portion. The tongue 25 is carried at theouter end of the top section 26 and adjacent its inner end this top section,

which is complemental in configuration to the bottom section 16, is provided at its side edges with lateral spring clips27 which are adapted to snap down over the. side edge flanges 19 and 20 of the base portion to hold the top section 26 clamped in secured position against the base portion. When the clips 27 are released the top section 26 may be swung upwardly on the hinge formed at its outer end by the engagement of the tongue 25 is provided with through the slot 24 in the lip and the clips 27 are snapped into engagethrough the slot 24 of the base section lip 23. At suitably spaced intervals the respective edge flanges 19 and 20 of the base portion are crimped to provide upstanding lugs 28 which are adapted to be engaged within recesses formed by upwardly crimped portions 29 in the edge flanges of the top section 26. These crimped portions serve as guides for proper positioning of the top and bottom sections when they are assembled in clamped relation with a blade engaged therebetween, and the lugs 28 serve to keep single edge blades from sliding out of position longitudinally.

As in a stropping operation it is important to restrain the holder and strop against relative sidewise slipping the lower and upper sections are respectively provided with spaced pairs of aligned upstruck guide lugs 30 and 31 extending from the apexes thereof.

At its apex the lower or base section 16 longitudinally spaced inwardly struck parallel lugs 32 having terminal lips 33 directed toward each other in a common horizontal plane slightly beneath the plane of the side flanges 19 and 20. These anchoring lugs 32 are adapted to be sprung apart slightly to engage a flat spline plate 34 at its ends beneath the terminal lips 33, which plate functions to hold double edge blades within the holder.

At longitudinally spaced intervals the spline plate is provided with perpendicular up-struck lugs 35 which are sufiiciently spaced for proper registry in the usual central apertures 36 which are characteristic of double edged blades known to the art at the present time. One of these blades indicated by the reference numeral 37 is shown in ap plied position in Figure 3 wherein the shank of the blade is disposed with its apertures 36 engaged over the holding lugs 35 of the spline plate with its edge portions 38 projecting beyond and overlying the edge flanges 19 and 20 of the bottom section.

The disposition of the lugs 32 holds the spline plate 34 against endwise movement and the engagement of the holding lugs 35 on the spline plate will retain the blade against shifting movement within the holder. The ends of spline plate 34 are formed with notches 34 which receive the shanks of the lugs 32 to retain the plate against lateral shifting within the holder.

In assembling the holder the top section 26 may be either swung up by reason of its hinged connection with the bottom portion or may be removed entirely therefrom as illustrated in Figure 9. The spline plate 34 is then brought into its proper engaged position in the bottom section and the blade 37 placed over the holding lugs 35. The top section 28 is then replaced with its tongue 25 passed base section end.

ment over the edge flanges 19 and 20 of the than the central lugs 30 and 31 with which they and retain 111 the base whereby the blade 37 will be firmly secured in position and the holder may be employed in connection with a stropping element, the oppositely inclined side faces of the respective top and bottom sections providing a proper angled engagement of the holder with the stropping element so that in manipulation thereover it is not necessary to lift the holder from its engagement with the strop.

A positive locking means comprising a key 39 is provided for retaining the sections of the holder closed over a blade. This may be used either with or without the spring clip 27. The key 39 is a fiat thin blank which, as shownin Figure 5, has an enlarged head 40, a central enlarged portion 41 of lesser size and an enlarged tip 42 of smaller size portion 41. In one position the key is adapted to be inserted through registering key slots 43 and 44 in the respective holder sections 16 and 26 after which it is given a quarter turn to engage the head and tip 42 over the respective sections thus locking the sections in closed position.

In the embodiment illustrated in Figures 7 to 14 inclusive like reference characters indicate parts identical with parts previously described. In this form the edge flanges 19 and 20 of the bottom section 16 are formed with integral laterally projecting flat guide lugs or ears 45 arranged as longitudinally spaced pairs. Similar ears 46 are formed on the edge flanges of the top. section 26 and are adapted to overlie the cars 45. These guide ears are arranged with slightly diverging opposed edge faces as best shown in F igure 7 positioned adjacent the respective guide cooperate in turning the holder upon a strop when a single edge. blade is retained in the holder. In Figures 7 to 14 inclusive there is also illustrated an alternative embodiment of the means for securing the sections in closed position. This means consists of a T slot 47 in the handle portion 21 adapted toreceive leg portion thereof the shank 48 of a locking finger extending from the inner end of the top section 26 and formed with a downturned head 49 which is adapted to pass through the head of the slot 47 and be retained under the apex of the handle.

In effecting this locking engagement the top section 26 is slid longitudinally over the bottom section, the engagement of the tongue 25 at the outer end through the slot 24 permitting the necessary play in the parts.

In Figure 15 is shown a locking means which may be employed in lieu of the key and slot shown in Figures 1 to 5. This means consists of a locking bolt having a shank 50 adapted to be passed through an aperture 51 at the apex of the top section 26 and to be threaded at its lower end into engagement with the -bottom section 16. An operating head 52 is provided on the bolt for engagement over the apex of the top section.

I claim a 1. ln a razor blade holder, complemental sections adapted to be connected to clamp a razor blade therebetween, lateral edge flanges he on said sections, and strop guide lugs integral with said edge flanges and extending laterally therefrom in the planes of the flanges in pairs spaced apart a distance greater than the length of a razor blade, said lugs having their opposed edges oppositely and outwardhaving upstruck lugs beyond each end of a a razor blade engaged in the holder whereby to provide strop guides, and guide lugs extending from the side edge flanges in the planes of the flanges, being disposed substantially in common planes transversely of the holder beyond each end of a blade carried in the holder.

In testimony whereof I aifix my signature.
